We have found a lot of miss information surrounding transmission service and what’s required. Information comes from auto manufacturers, automotive manufacturing dealers, general auto repair shops, lube shops, oil companies, car washes, back yard mechanics and transmission shops. When you ask all of these, rarely will you get the same answer when it comes to how you should take care of your transmission. You have to realize that each of our trusted sources comes from some completely different perspectives, backgrounds and knowledge bases, and most of these have been subject to inaccurate information themselves. Most of these sources would gladly tell you they don’t really understand the inside of a transmission, maybe just a conceptual understanding.

Tri-City Transmission’s perspective & recommendation comes from this; performing thousands of transmission overhauls & hundreds of thousands of transmission services over the last 37 years. We live, eat and breathe transmissions. It’s our passion! We perform costly repairs on transmission that could have been avoided had the transmissions been properly serviced & maintained regularly. The transmission is the second most expensive component in your vehicle, who do you want to entrust your transmission to.

All Our Preventative Maintenance Services Include "Factory Fill" assuring the service meets the requirements of upholding the factory warranty. This has been widely overlooked in the industry, However, there are specific transmission fluids your car requires and based on experience, Tri-City Transmission Service is adamant about "Factory Fill".

Here are our rule of thumb service intervals:

Automatic Transmissions, Annually or Every 24,000 miles

Standard Transmissions, Bi-Annual or Every 30,000 miles

Transfer Cases, aka 4WD or AWD, Every 3 Years or 45,000 miles

Differentials, Bi-Annual or Every 30,000 miles

In most cases our rule of thumb recommendations meet or exceed factory recommendations. Often times we find factory recommendations to be light or non-existent. Some manufacturers say no service at all even when their technology in the transmission is no different than that of the next manufacturer who recommends frequent service. Also, one of the myths we often have to dispel is that your transmission is a sealed unit and service is not needed. We have yet to run into a sealed transmission – Try to remember maintenance free batteries in Arizona and how long they lasted. Automobile manufacturers are not only in the business of selling cars, but also transmission parts.

Our recommendations & factory recommendations do vary depending on vehicle make, model and fluid type. Intervals provided above are the most common. Consult your factory manual provided with your vehicle or don’t hesitate to call us for more details.
